Beet armyworms (BAW): Has 5-6 generations in the south. Host
plants include bean, corn, cowpea, eggplant, pea, pepper, potato, tomato, and
many other vegetables. Field crops may include corn, cotton, peanut, sorghum,
(FAW): Has 4-5
generations in the south – migrates upward from FL and populations get worse
mid- to-late-season on specialty or row crops. Prefers to feed on grasses then
move to various row crops and vegetables that include fruiting crops.
Fall armyworm moth activity has
increased in the past two weeks indicated by the spike in the graph (average
moth numbers = 4.2). Activity of FAW moths has been very high in Lee, Clanton, Cullman,
and Limestone counties indicating a possible migration of second or third
generation moths to row and horticultural crops. Hay and livestock producers should
for update about armyworms (updated by Dr. Kathy Flanders).
Soybean looper (SL): Infestations happen from migrating
populations or moths may be moved by weather systems. SL attack soybean and
peanuts among other row crops. Also attacks many summer vegetable crops during
Cabbage loopers (CL): We have a few locations across AL where we
are monitoring this highly migratory insect. Adult moths are known to
overwinter in south Florida. Host plants include a variety of crucifer crops
along with sweet potatoes, beans, peas, squash, tomato, and watermelons.
Corn earworm (CEW): Also known as the tomato fruitworm. It has
about 5-7 generations in the south. Corn, tomato and cotton appear to be
favorite crops among numerous others row and horticultural plants that may also
be attacked. In Alabama, peak CEW activity usually happens in late July and
August – so remain alert for CEW and tobacco budworm mixed populations.
Tomatoes are a favored host for CEW moths to lay eggs if corn is unavailable –
so vegetable producers should watch out and scout intensively to detect this
pest at the earliest!
(TBW): Has about 5 generations in the south. Host
crops include cotton, soybean, and peanuts among others. May also attack
vegetables as pea, pepper, pigeon pea, squash, and tomato.
CEW/TBW pest status update: This has been an
interesting year for these insects with very slow increase in moth activity across
the state. Last week we noticed a sharp increase in the number of CEW moths at
about half of monitored sites (average = 2 moths per trap). Tobacco budworm activity has been erratic with detection
of at least one moth at 40% locations. Cullman, Lee, Brewton, and Barbour
counties have had the most TBW moth numbers.
cornstalk borer (LCB):
3-4 generations may occur. Prefers various legume (including peanuts and
soybeans) and grassy crops. In peanuts, LCB damage can cause rapid yield loss
along with severe crop contamination during hot dry weather conditions. This
insect can also devastate large acres of soybean fields under favorable conditions.
Has one to two generation per year depending on location. Moths are day-flying
and they can migrate long distances during early spring to find host plants. Moths
look like wasps and lay eggs on the stem close to the soil. Caterpillars cannot
be killed once they burrow inside the plant stalk, so use pest prevention
tactics. Vines must be protected using insecticides or with insect netting to
reduce egg laying.
SVB pest status update: We are continuing to monitor this insect in
order to record season-long activity and life cycle fluctuations. Moth numbers
have decreased from 7 moths per trap to 3 moths per trap in about two weeks. It
appears we are now detecting a second generation of these moths at the research
farms. This is an insect pest that can be the final killer for squash plants after cucumber beetles and squash bugs have done their damage to the crop.
